Summary: decimal module borks thread

Initial Comment:
I got across this while trying to use MySQLdb in a
thread. Since MySQLdb imports decimal I got the same
error there.

Code: (This happens in both 2.4 and 2.5)

import thread, time, sys
if len(sys.argv) > 1:
   import threading

def test ():
   import decimal
   print 'Exiting test.'

thread.start_new_thread(test, ())
time.sleep(1)


Output:
$ ./thread.py 1
Exiting test.

$ ./thread.py
Exiting test.
Error in atexit._run_exitfuncs:
